One of the characteristics of unbelief is that it always puts the answer off into the future. Things used to happen and someday they'll happen again but nothing ever happens now. Jesus taught that the time was fulfilled, the Kingdom of God was here. No more waiting. In fact, that was Jesus assignment, to establish the Kingdom of God on the earth. You can see this in scriptures that talk about Jesus authority and power. Scriptures that talk about the authority he has won, about the authority he was awarded.
